Research ArticleOpen accessIn the keywordsNifH: Structural and Mechanistic Similarities with Proteins Involved in Diverse Biological ProcessesSurobhi Lahiri, Lakshmi Pulakat, Nara GaviniThe NifH protein is a subunit of the nitrogenase enzyme that catalyzes the reduction of atmospheric nitrogen to ammonia. This protein contains highly conserved regions including the nucleotide binding sites, metal center ligands and the Switch I and Switch II domains. A number of proteins have structural and mechanistic similarities as well as evolutionary relationships with the NifH protein, notable … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Endoribonuclease Domain of IRE1 and its Substrate HAC1 are Structurally Linked Components of the Unfolded Protein Response in FungiLuis David Maldonado-BonillaThe unfolded protein response sustains the folding capacity of the endoplasmic reticulum under conditions that increase the activity of the secretory pathway. In fungi, the unfolded protein response exclusively depends on the kinase/endoribonuclease IRE1, which senses the accumulation of unfolded proteins in the endoplasmic reticulum lumen and catalyzes the committed step in the unconventional splicing of HAC1 mRNA that encodes … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 14 Oct 2020 · 6,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Consumer Awareness of Energy Efficiency in Saudi ArabiaSamar Khan, Hafez Abdo, Abdulrahman Al-GhabbanScholars have been interested in energy efficiency/conservation and consumer behaviour for over 35 years and research in this domain continues to grow. Energy efficiency and conservation are significant policy tools that can be introduced by governments to help save the environment. The kingdom of Saudi Arabia possesses a wealth of energy resources. The exploitation of these resources has allowed the … …Energy Research Journal, Vol. 6, Issue 1 · 25 Apr 2015 · 9,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractEast Kolkata Wetland: A Multifunctional Niche of International ImportanceI. Mukherjee, S. Ray Chaudhuri, D. Ghosh, A. R. ThakurProblem statement: In the megacity Kolkata, the need for space to accomodate the ever increasing population is increasing day by day. As a result the encoarchment of the large wetland on the eastern frindge of the city is increasing and so is the threat of its loosing the status of Ramsar Status. Approach: Proper documentation of the existing traditional practice … …OnLine Journal of Biological Sciences, Vol. 12, Issue 2 · 31 Jul 2012 · 9,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Heat Transport in a Proton Exchange Membrane (PEM) Fuel CellE. Afshari, S.A. JazayeriIn this study a two-phases, single-domain and non-isothermal model of a Proton Exchange Membrane (PEM) fuel cell has been studied to investigate thermal management effects on fuel cell performance. A set of governing equations, conservation of mass, momentum, species, energy and charge for gas diffusion layers, catalyst layers and the membrane regions are considered. These equations are solved numerically in … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Comparison of Thermal Stratification due Natural Convection in Densified LOX, LN2 TanksSeyed Ali Jazayeri, Ehsan Molla Hasanzadeh KhoeiThe growth of natural circulation and thermal stratification inside LOX, LN2 storage tanks due to heat transfer from surroundings is investigated using a non-equilibrium, two-domain, mathematical model. The two-dimensional model is considered for the liquid domain in two cases and a lumped, thermodynamic model is utilized for vapor domain. The vapor is assumed to behave like an ideal gas. The … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,971 accessesView PDFCite
